Perhaps youve already heard about fuel cells or even about hydrogen fuel cell car. Yet, only a few knows how it works and why it is very important in the coming years. Global warming poses a great threat to the Earth and one way to address such problem is to look for an alternative source of energy.
Great attention is now focused in the production of fuel cells for automobiles. In fact, car manufacturers are designing sophisticated cars that make use of the hydrogen technology. A good thing about using hydrogen fuel cells is that the byproduct is not harmful to the environment. By using the fuel cells, oxygen is eliminated which is also needed by humans.
Experts compare fuel cells with batteries but there is a great difference. The fact is batteries go down but the fuel cells dont. The fuel cells are able to produce the needed car energy through a process called electrolysis. You can find 2 electrodes and 1 electrolyte in a fuel cell. The oxygen and hydrogen will be separated and after the whole process, heat and water will be produced.
The hydrogen molecules will go to the anode and the oxygen molecules to the cathode. The fuel cell can use the hydrogen...
